Jessica Simpson looks undeniably pregnant and experts say she appears to be about six months along.

“She looks to be 26 weeks, which is around six months,” OB-GYN Dr. Dave David told Radar. “It is definitely a pregnancy and not weight gain. You can by the shape of her abdomen. Her belly wouldn’t be that rounded if it was just fat.”

While Simpson covered her belly with a red coat last night while heading to dinner with friends in New York, it was too late — her photo was snapped in a tight-fitting shirt earlier in the day, revealing a very rounded stomach and protruding belly button. But she is still not addressing the issue with the press because, as Page Six reported, she was holding out for a magazine deal of $500,000.

Instead, Simpson tweeted on Monday “Short girl problems,” along with a strange image showing a woman — presumably her — sitting on a commode with her feet dangling inches from the floor.

Meanwhile, Simpson’s ex-boyfriend Tony Romo announced yesterday that he and his wife, Candice Crawford, are expecting. Perhaps he and Simpson’s child can grow up best friends?
